Configure
Ports
on
the
8-Port
Asynchronous
Adapter
The
default
configuration
for
ports
on
the
8-port
asynchronous
adapter
is
for
RS232
ports.
To
use
RS422
cables
on
the
adapter,
the
adapter
must
be
configured
to
accommodate
them.
For
configuration
instructions,

Install
and
Configure
an
128-Port
Asynchronous
Adapter
The
128-port
asynchronous
adapter
is
an
option
for
the
HMC.
It
must
be
configured
by
the
service
representative
when
the
HMC
is
installed.
The
128-port
asynchronous
adapter
software
is
installed
in
the
HMC
base
software-installation
package.
This
adapter
provides
the
control
function
and
connectors
to
attach
eight
16-port
remote
asynchronous
nodes
(RANs).
When
all
eight
RANs
are
attached,
this
combination
provides
128
RS232
or
RS422
communication
ports.
Refer
to
the
illustrations
shown
in
“HMC
to
Processor
Subsystem
Cabling”
on
page
24
for
cable
information.
The
bottom
portion
of
the
illustration
shows
the
128-port
adapter
and
the
RS232
cable
pairs
to
support
up
to
64
processors.
There
are
16
RS232
ports
per
RAN
unit.
Up
to
four
RAN
units
can
be
daisy-chained
on
one
128-port
asynchronous
adapter.
The
RAN
unit
has
Ethernet
(RJ45)
connectors
that
connect
to
the
25-pin
D-shell
male
connector
on
the
RS232
cable.
To
install
and
configure
the
128-port
asynchronous
adapter,
refer
to
the
IBM
Hardware
Management
Console
for
pSeries
